Geografy of Iran
Iran as a Four Seasons Country
The Iranian plateau today is a land surrounded by high mountains and spotted by warm lowlands. Two important mountain ranges, each with peaks over 5,000 meters high, stretch from the northwestern corner of the plateau, the current Azerbaijan province, to the south and east. The eastern branch, Alborz, boasts the highest peak of the two ranges, Mt. Damavand. The Alborz range creates a high barrier south of the Caspian Sea, making serious impacts on the climate of the plateau. While lush forests and pastures abound south of the Caspian and give it a mild, humid weather, the Alborz prevents the passing of the rain-rich clouds to the inside of the plateau, causing very low rainfall, and thus creating a dry and mostly warm climate south of the mountains.
The second mountain range, Zagros, stretches from northwest to the south and diverts to the east just north of the Persian Gulf. It does not cause as much complications as the Alborz, since the height of the Zagros peaks decrease around the Persian Gulf, allowing more clouds to move over the mountains. In areas were Zagros forms two branches, just south of Azerbaijan; an inhabitable area has been created that shows some of the oldest signs of settlement on the plateau.
Inside the country, there are two major deserts; one, Dasht-e Kavir, around 200 km east of modern Tehran and at the feet of the Alborz range, is covered with sand and is mainly uninhabited. The smaller desert, Lut, is not as dry and provides enough resources for the survival of small communities. These two deserts, both pushing towards the east, have caused the shift of population to the west, north, and south of the plateau.
In addition to the southern Caspian region, two more regions, one north of the Persian Gulf and east of the point of the meeting of Tigris and Euphrates, and the other at the point of meeting of the Persian Gulf and the Sea of Omman, are agriculturally very prosperous. .
The rivers of Iran are few and mainly seasonal. From the major rivers, only Karun in the south, Aras in the northwest, and Sepid-rud in the north flow year round, and only Karun is deep enough for modern navigation.
The capital city of Iran is Tehran, a diverse and wondeful city that offers everything from traditional Iranian culture and architecture to modern services and buildings.
